The G65-WB37N model comes with a Samsung zoom module, capable of 37X optical zoom with a variable total zoom capability of 444X (37X optical and 12X digital). High resolution of 550 TV lines at color mode and 680 TV lines at B/W mode can be achieved by using a high density SONY CCD that has double speed of 410,000 pixels, which provides clean, noiseless and reliable pictures. By using the DSP chip applied to the DNR technology, the amount of low illuminance noise has been significantly reduced, and the signal-to-noise ratio (S/N) as well as horizontal resolution has been improved, resulting in a clear and sharp image display even in the dark. Additional benefits of G65-WB37N include Day & Night (IR) Infrared Cut-Filter Removable and the user friendly "On Screen Display" (OSD) menu, which facilitates operation of all functionality, including PTZ via the AVUE controller or a standard DVR.
